Here are the reading of the characters
肖 - xiào: similar, resembling, to resemble, to be like - Xiāo: Surname
素 - sù：essence, nature, element, plain, white etc.
However, (re. your Jan.24 posting) do not forget that on your vase in front of 肖 there is a stylized standing lizard, which is actually Radical 162 "walk" 辵 in the Kangxi Dictionary.
Therefore 辵＋肖 makes the character 趙 "Zhao"
I have encountered this standing lizard variation
The other side, lizard behind 素 is new to me, but the analogy can be applied here too.
糸+此 → 紫 Zī
On the other hand, the irregular but generally accepted character order from left to right was necessarily determined by the radical of character Zhao
